Texture details in eyes and hair influence the impression of character illustrations. Generally, these details are not expressed in line drawings, but in colorization in color illustration production. Many existing automatic or semi-automatic colorization methods do not target hand-drawn line drawings and it is difficult to paint texture details on such drawings. In this paper, we propose the semi-automatic colorization of character line drawings around faces with texture details. Our method uses a reference image as a color hint and transfers the textures of the reference image to a line drawing. To achieve this, our method uses segmentation masks to match parts of the line drawing with the same parts of the reference image. We create two types of segmentation datasets to train a segmentation network that creates segmentation masks. We transfer texture details to a hand-drawn line drawing by mapping each part of the reference image to the corresponding part of the line drawing using segmentation masks. We show that our method is more effective for hand-drawn line drawings than existing methods using qualitative and quantitative evaluations.. |

| 3. | Kohei Doi, Yuki Morimoto, Reiji Tsuruno, Global Illumination-Aware Color Remapping with Fidelity for Texture Values, SIGGRAPH 2021, 2021.08, [URL], Our aim is to convert an object’s appearance to an arbitrary color considering the light scattering in the entire scene, which is often called the global illumination. Existing stylization methods convert the color of an object with a 1-dimensional texture for 3-dimensional computer graphics to reproduce a typical style used in illustrations and cel animations. However, they cannot express global illumination effects such as color bleedings and soft shadows. We propose a method to compute the global illumination and convert the shading to an arbitrary color. It consists of subpath tracing from the eye to the object, and radiance estimation on the object. The radiance is stored and used later to convert its color. The method reproduces reflections in other objects with the converted color. As a result, we can convert the color of illumination effects such as soft shadows and refractions.. |

| 5. | Kenta Akita, Yuki Morimoto, Reiji Tsuruno, Fully automatic colorization for anime character considering accurate eye colors, ACM SIGGRAPH 2019, 2019.07, In this paper, we propose a method to colorize line drawings of anime characters' faces with colors from a reference image. Previous studies using reference images often fail to realize fully-automatic colorization, especially for small areas, e.g., eye colors in the resulting image may differ from the reference image. The proposed method accurately colorizes eyes in the input line drawing using automatically computed hints. The hints are round patches used to specify the positions and corresponding colors extracted from the eye areas of a reference image.. |
